Ernesto Valverde says Barcelona suspect star signing Ousmane Dembele suffered a torn hamstring against Getafe.
Dembele had to be withdrawn in the first half of his side's dramatic 2-1 victory on Saturday, leaving the field after sustaining the problem while attempting a back-heel near the corner flag when the match was still goalless.
Barca confirmed during the game that the 20-year-old had suffered the problem in his left hamstring during what was his full La Liga debut and would undergo tests to determine the severity of his injury.
And Valverde fears it is a muscle tear, although he will wait until he has a definite diagnosis before speculating over how long Dembele will be out.
